摘要

The aberrations due to the variation of the refractive index with wavelength (dispersion) are usually termed "chromatic aberrations". Originally this wording was based on the fact that in the presence of these aberrations, the image of objects like points, lines, edges exhibit - in addition to the variation of luminance - coloured fringes.From this point of view, the concept of the Point Spread Function (P SF) and the related Optical Transfer Function (OTF - ISO 9334) is basically a luminous (or more general radiative) transfer of optical information. There is only one signal - regarding to wavelength - which is the result of the spectral transmission and sensitivity of the transmission chain, even if the latter is not identical to the relative luminous sensitivity of the human eye.
